+### Certification of Cardano stake distribution
+
+We have introduced the certification of **Cardano stake distribution** with the release of the new distribution [2442](https://github.com/input-output-hk/mithril/releases/tag/2442.0).
+
+This update leverages the Mithril network to provide certified Cardano stake distribution data without requiring a full Cardano node, which is particularly useful for applications such as bridges, sidechains, and layer 2 solutions.
+
+Key changes include:
+
+- Certification of Cardano stake distribution at each epoch transition.
+- New HTTP routes in the Aggregator REST API to access this certified data.
+- Updates to the Mithril client library and CLI for retrieving and verifying Cardano stake distribution.
+- WASM client support for these functionalities.
+- Mithril Explorer now displays certified Cardano stake distribution.
+
+For any inquiries or assistance, don't hesitate to reach out to the team on the [Discord channel](https://discord.gg/5kaErDKDRq).
